batman_adv: bat0: The MTU of interface adhoc0 is too small (1528) to handle the transport of batman-adv packets. Packets going over this interface will be fragmented on layer2 which could impact the performance. Setting the MTU to 1546 would solve the problem.

Did you enable network coding? That would explain the message, as NC uses a larger header to make decoding possible at the receiver side.

As far as I can tell from a quick look in packet.h, the required MTU should be 1532 now. (10 bytes unicast + 8 bytes extra for unicast_4addr + 14 ethernet = 32 bytes). Or am I bad at counting bytes?
